McLaughlin was a fellow California hard edge abstractionist working in the same era whose oil paintings feature precisely rendered geometric rectangles in limited bold palettes with the same razor sharp edges and meditative optical tension seen in Two Timer.

Benjamin was one of the four Los Angeles hard edge painters exhibited alongside Hammersley in 1959, creating interlocking geometric forms in bold chromatic palettes with the same crisp precision and optical vibrancy that defines Two Timer.

Feitelson co-founded the Los Angeles hard edge movement and produced paintings featuring overlapping rounded and geometric forms in bold red, black, and white palettes rendered with the same precise flatness and visual tension as Two Timer.
